Keeping this in consideration, can I use my phone as an external webcam?
If your phone runs Android, you can use a free app called DroidCam to turn it into a webcam. To get started, you'll need two pieces of software: the DroidCam Android app from the Play Store and the Windows client from Dev47Apps. Once both are installed, make sure your computer and phone are on the same Wi-Fi network.
Secondly, how can I use my phone as a webcam without an app? Use your phone camera for video chats instead
- You don't even need a webcam app. A dedicated webcam app (more below) has special features, but you don't have to have one to use your phone camera for video chats.
- Find and download the right webcam app for Android or iPhone.
- Use your phone's main camera.
- Stabilize your phone.
- Set up some lighting.
- Invest in a microphone.
Just so, can I use my cell phone as a security camera?
As long as your device has a working camera and microphone, you can use it as a security cam. You can install the Haven beta from the Google Play Store or compile it yourself from its Github repository. Haven will work whether your phone is connected to Wi-Fi or with a USB-to-Ethernet adapter.
How can I use my smartphone as a USB camera?
Use your android phone as webcam using USB.
Connect the phone to your computer via USB (don't select storage mode if the phone asks while connecting USB). Download DroidCam from android market,install it and open it on your phone. It will show a "Starting server" message.
